Correct tyre pressures
Hello all. I know that the manual suggests 37 front and 44 rear, but when the tyres warm up that's 43/4 front and 50/52 rear according to my TPMS. I took the car on some twisties today (Lake Hughes Rd., - great driving road!) and the tyres squealed through every turn. Do any of you guys run less pressure than that? Thanks all.

I've been running 37/44, Irish. PS2 tires, no squeal issues. I don't have TPMS, but I've checked the tires hot and am seeing about a 6psi increase, so we're in the same boat.
I have 3,500 miles on the C4S... the PS2s are wearing evenly, but FAST!

I am running the stock 33/39 pressures. I just got my car yesterday and drove it home from the dealer and then check it pressures this moring and they had it at 40/46 so I lowered them to the stock settings. the car now goes over the highway expansion joints much better in the turns/on/off ramps

Singing tires!
Singing tires are happy tires, so goes the motto at PDE!
You need to get up in the middle of the night when the ambient temp is about 68 degrees, and with a race style (accurate) tire pressure guage, set the tires to exactly 33/39. This is called Porsche passion
Then after the tires come up to temp, measure what it says on the TPMS and keep the readings for future reference...Forget about "micro" adjustments and keep the the TPMS turned off, otherwise it will drive you crazy, because of minute differences side to side, etc. Example, which side of the car faces the sun!
Seriously, keep it at 33/39 and forget about it, then "sing" away!

I run 36/39--seems to handle a bit more neutrally for me at those pressures.

I personally love having the near real-time feedback that TPMS provides. It is that extra confidence factor when I start to feel or hear things from the tires. Nope,--that must be the road! I start my days at 33/39 and they wind up around 37/44, roughly
